REMOTE-CONTROL SYSTEM.

Application filed January 25, 1921.

To all whom it may concern -Be it known that I, PAUL KAMINsKI, a citizen of the German Empire, residing at Berlin-Pankow, Germany, have invented certain new and useful Improvements in Remote-Control Systems, of which the followis a specification.

My invention refers to remote control systems and more particularly to the controlling from a distance of guns or other apparatuses. The remote control systems employed up till now, having mechanisms for coarse and fine adjusting of the elevation of guns or other apparatuses relatively to they object aimed at, operate satisfactorily in all cases in which the guns or the like are disposed at substantially the same level. If, however, they are located at different levels,.such as for example the guns, search-lights or other inm struments on board a ship the-re result con-r siderable differences in the adjustments of such apparatus as are not disposed at the ob servers level.

It is an object of the present invention to adapt control systems of the kind afore-mentioned to plants in which the guns or other apparatuses are arranged at difierent levels, the mutual distance between the guns being small as compared with the distance from so the object aimed at. For this purpose a special mechanism for fine adjustment is provided for each level which differs from that of the observers station, and a .parallactic correction is applied to this mechanism in 5 accordance with thendifierence between the levels.

In the drawings afixed to this specification and forming part thereof a system embodying my invention is diagrammatically illus-v do trated by way of example. In the drawig. 1 is a diagram showing the trajectories of missiles fired at an object from two different levels, and

Fig. 2 is a diagram of an observers station and two gunscontrolled thereby:

As shown diagrammatically in Fig. 1 of the drawings, for a certain vdistance Z from the object aimed at the guns or instruments lo cated at the level a; must be adjusted in ele vation to the angles. If other guns situated at a level 3/ difiering from the level iv by the distance i were elevated by means of the same remote control system to the same angle e these guns would not hit the object.

Serial No. 439,894.

Therefore, a difi'erent angle of elevation must be adopted for the guns located at the level 3/. This angle is determined by the difierence of level it and the distance 6 between the upper guns and the mark, and is e{5, wherein it results from the value sin (5: e Since for all practical purposes the difierence between the distances Z and e is exceedingly small, and h as compared with Z is very small too, the angle (5 will also be very small, so that in the above value sin (5 may be safely replaced by tg 5:25

In reducing my invention to practice the remote control devlce, used up till now and comprising mechanisms for coarse and fine adjustment, is retained for all those guns which are located at the observers level (Fig. 2). In accordance therewith the device a for setting the distance operates the transmitting device G, for coarse adjustment by means of the bevel'wheels b, 6,, 0, 0,, the planet gear (1, the worm gear 7 and the toothed wheel gear g. At the same time the transmitting device for fine adjustment G is set correspondingly by means of the bevel-wheels i, i, and the toothed gear wheels 70, 70,, Z, Z The movements of the coarse transmitter G, and the fine transmitter G are then transmitted in a well known manner to the coarse receivers E and fine receivers E, adjusting the Obviously it is immaterial for the purpose of my invention whether the receivers E, E, on the guns are in the nature of indicators acting on the follow-the-pointer principle or if they act directly upon the power plant of the gun. Furthermore, it .is immaterial whether they are connected to the pointing 'mechanism of the gun or to its sight-setting ted to thespecial fine transmitter G'r by means of the bevel gears 77, b 0, 0,, planet gear (1, spindle t, bevel gears u, a planet Eli the upper guns 3 This additional movement adds to the transmitter G the amount of of the aforementioned formula. Since in this amount to be imparted to the gear 11, h is a constant, Z represents a certain ratio of the variable Z. Inasmuch as the setting device a, and therefore bevel gear m is turned corresponding to Z, i. e., the range, I vary this movement according to the aforementioned formula by the gearing n, p, the pitch oithe thread of the spindle n corresponding to the factor k. v

When the spindle n turns on its axis, the nut of pin 0 will travel on it, and the pin 0, suitably engaging the guide 9, pulls or pushes the latter the desired amount. Guide p, the axis of which is parallel to the spindle n is slidably mounted in the apparatus casing, not shown here.

Obviously any other suitable gear mechemme anism may be employed to transmit the above-mentioned desired amount of inclination correction to the fine transmitter G If the guns are mounted on an oscillating platform such as a ship or air craft the oscillations are compensated for in the usual manner by means of the telescope F and toothed or bevel gearings D transmitting their movements through sleeve B to the planet gear 03 and thereby influencing all the transmitters of the remote control system.

A special fine transmitter G actuated in a similar manner is provided for each additional series of guns placed at a different level.

\ I claim:

In an electric signalling system for transmitting the angle of inclination to a battery of guns or the like, which are mounted in different horizontal planes, in combination, electrical transmitters for each of the different planes located in a central station, means mechanically connected with said transmitters for setting the range, mechanical means for imparting to said transmitters the required amount of correction of the range, due to the difierent planes in which the guns are mounted, said means being actuatedby said setting means, and electrical receivers on the guns connected to said transmitters.

lin testimony whereof I aflix my signature.
